例：Such customs are widely accepted.
这样的风俗是被普遍认同的
2.So whatever he accepts in exchange for his fish can not be something acceptable only to the suit-seller.因此，无论他用这船鱼换到什么物品，这件物品不能仅仅是这位卖衣服的人愿意接受，还必须是所有其他人都愿意接受的物品。
(1)此句中的whatever he accepts in exchange for his fish是主语从句。
whatever pron. everything or anything that无论什么，任何东西，一切事物
例：Do whatever you please.
你喜欢做什么就做什么
(2)acceptable only to the suit-seller是由形容词acceptable引导的"形容词短语"，做后置定语，修饰前面的不定代词something。
3.When everyone is confident that everyone else will accept something as money, then that something becomes generally acceptable. 当大家认识到人人都愿意接受某种物品为货币时，这时它就会被普遍接受。
(1)be confident that…:相信…；认识到…
(be confident) that…,(then) that…:是两个并列的宾语从句。
(2)become generally acceptable被普遍接受
